ORNAMENTAL CHAIN.

SPECIFICATIQN forming part of Letters Patent No, 365,115, dated June 21,1887.

Application filed May 10, 1887. Serial No. 237,093. (No model.)

To aZZ whom, it may concern.-

Be it known that I, SIDNEY O. BIGNEY, of Attleborough, in the county ofBristol and State of Massachusetts, have invented a new and usefulImprovement in Ornamental Chains; and I hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

This invention. has reference to an improvcment in the construction ofornamental chains, as will be more fully set forth hereinafter.

Figure 1 is a side view of the improved chain 011 an enlarged scale.Fig. 2 is a face view of the same, and Fig. 3 is a sectional Viewshowing one of the connecting-links be fore the same is closed.

In the drawings, a a a are the links forming the main portion of thechain. They may be of any desired form or size, but are usually smallrings, such as form the units in what are known in the art as rollerchains.

b b are the connecting-links, usually bent from wire, and preferably ofsquare or nearly square cross-section.

c c are short pieces of tubular wire.

Thelinks a a, connecting-links Z) Z), and pieces of tubular wire havingbeen first formed, the connecting-link is passed through the link a, thetubular wire 0 is inserted into the next link a, and the ends ofconnecting-link b are forced into the piece 0 of tubular wire. The

corners of the square connectinglink bearing against the interiorsurface of the tubular wire firmly retain the ends, and they do notrequire to be secured by solder, thereby causing a large saving inlabor, and also producing a chain more flexible than a soldered chain,while the same is equally as strong.

The tubular-wire pieces 0 inserted into the main links a greatlyincrease the ornamental appearance of the chain, and, as the wear comeslargely on these pieces c of tubular wire, the durability of the chainis materially increased.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In an ornamental chain, the combination, with thelinks a a and the connecting-links Z) I), of the tubular pieces 0 o,constructed to receive the connecting-link, as described.

2. The combination, with the links a a and connecting-links b I), of thetubular pieces 00. constructed to receive the ends of the connecting-links, as and for the purpose set forth.

3. The combination, with the links a a and connecting-links b b, of thetubular pieces a 0, constructed to receive the ends of theconnectinglinks and secure the same by frictional contact, as described.
